Part Number: BQ21080 Tool/software: Hello,
If the power is removed (neither VIN nor VBAT), will the BQ21080 store the user configurations? Or will it revert to the default settings?
Also, which are the default settings?
Thank you.
Best regards,

Part Number: BQ21080 Tool/software: We are in need of information on the UBM (Under Ball Metallization)/SRO (Solder Resist Opening) of this device BQ21080YBGR
We need this for our DFM team to define their own land pattern.
Thank you,

Hi Dushyantha,
There is a slight increase in Ibat_active, about 2 uA as compared to /LP being pulled to VDD, but aside from that the device behavior appears to be as expected so this connection should be fine for your solution.
You won't be able to disable…
Part Number: BQ21080 Tool/software: Dear TI Engineer,
We are wondering what is the minimum voltage threshold for the TS/MR pin of BQ21080 in response to long pressing the external power button to exit ship mode. That is, what the voltage of TS/MR pin…
Part Number: BQ21080 Tool/software: We are using a 0.5W 5V solar panel connected to the BQ21080 to charge a LiFePO4 battery. We have programmed a 2.8V Battery Undervoltage LockOut, enabled VinDPM as pseudo MPPT, and 100mA charge current.
In some situations…
Part Number: BQ21080 Other Parts Discussed in Thread: BQ25180 Tool/software: Hi, TI engineer.
right now I use the part BQ21080.
The charging current is set to 700mA, but at +55°C, the measured current is 550mA.
During charging, the…
